.TOaZZ zii/1.0971,z5mayconcefln.tvv c n, Be it known that I, HERMAN MEnTEN, a citizen of the U nited States, residing in New York, countyof Queens, and Statefof New York, with post-oflice addressfat 430 Sher-4 man street, Astoria, New YorkyN. Y.,have invented certain new and useful Improvements in Safety Gas-Burners, of whicli'fthe` following is a'specifi'c'ationj v This invention relates to safety gas burners and especially t0. gas burners for stoves or other devices in which the gas is used for heating. y

The invention is particularly applicable to burners in which the flame is concealed from view, though it is also applicable to any other type of gas burner.

The primary object of the invention is to provide a gas burner of such construction that when the need for the gas flame ceases the flow of gas will be automatically cut of and a signal operated to indicate that the gas is no longer required. 1

In the accompanying drawings I have illustrated two embodimentsof my inven-v tion which differ in respect to the character of the signal employed. y In the drawings: Figure 1`is a view principally in vertical longitudinal section of improved gas burner provided with ay mechanically operated bellto serve as afsigL nal. Fig. 2 is a plan view of thestructure shown in Fig. 1. Fig. 3k is aj perspective view of an electric bell connected with the burner -to serve as a signal. 1

I have illustrated my improved burner as applied to a heating stove'and'have shown a conventional yarrangement of parts for i such abiirner together with the novel elements which in combination comprise my invention. f l n t ln the drawings, 1 designates a gas chamber of suitable kform having perforations l in the top where the gas is'. ignited. The

gas chamber is of the usualannular form and in the center is a guide 2V through which passes a vertical standard 3 which carries on its upper end a` spider 4 upon which any vessel orother body to be heated Imust be placed. The lower end of--the` standard 3 rests upon one varm o-f a bell `crank lever 5 the other arm of which is connected by a link G with a second bell crank lever 7 which operates a valve 8.

which controls the iowof gas to the chaniber 1. A weight 9 is attached to one arm @getTime-f if of thebellcrank lever7 and .-rests, las'shown.- I

in Fig. 1, upon any arm. 11.0 which Icontrols; theg y mechanism-ofthe signalbell` .11. 1A smalll` bore .tube l2 extends from the ,valve 8- to the burnerand,servesasa pilot `light so long as the cutiofll valve 13de open. i

The operation of the safety gas burner l' parts are shown in Figs. 1 and 2 in the position in which they are left immediately `after removing from the burner the body which has been receiving heat. rlhe weight 9 acting upon the bell crank lever 7 has raised the spider 4 and has itself descended upon the arm 10 upon the bell 11.l 'Ilie 4movement of the bell crank lever 7 under the action of the` weight h as closed. the valve 8 and cut ofi" the supply of 'gas to the chamber 1, and has also caused the bell 11 to begin ringing, thus calling attention to the s fact that the supply of gas to the burner has been cut off but the pilot light is still "burning. If the burner is to be used again in a few moments the personv in charge will simply swing the weight 9 to one side so as to release the arm 1() and stop the ringing` 4"z ilbove described 'will be readilynnderstood yfroinfthe description and drawings. The4 of the bell 11. If the burner is not to be used in the immediate future the person in charge will not only stop the ringing of the bell by swinging the weight 9 olf the arm 10 but will'use the valve 13 to cut off the flow of gas to the pilot light.

. The' next time abcdy to be heated is placed on the spider 4 the weight of the body will depress the spider thereby operating both crank levers'afnd opening the valve 8. yThe ymovement 0f the bell crank lever'7 when the valve 8 opensk will raise the weight 9 so that it will swing into position above the arm 10 inreadiness to setthe bell in action as soon as the body to be heated is removed froml the burner.
